Weight of travel trailer

I agree with what Nickthehunter just said. A tow rating is a decent place to start but....few half tons can actually tow the maximum weight stated without having troubles in other areas. I tow a 6500 lb trailer with my Tundra that (they say) can tow 10K lbs. With a TW of close to 1000 lbs I am close to my payload number before I even start the engine. So, look at axle ratings and payload capacities when you start to narrow your choices.
